1.3.2 Resource isolation mechanisms - On this episode, we dive into the essential AWS resource isolation mechanisms, which are crucial for responding effectively to security incidents in the cloud. We explain how isolating compromised resourcessuch as EC2 instances and S3 bucketscan help contain threats, protect unaffected data, and preserve valuable forensic evidence. Youll hear about key AWS tools like VPC, IAM, Security Groups, Network ACLs, and automated solutions using Lambda and Systems Manager that enable rapid, scalable isolation and response. We also cover best practices, including preconfiguring quarantine environments, enforcing least privilege, automating responses, and ensuring forensic integrity with measures like S3 Object Lock. Practical scenarios demonstrate how to integrate these techniques with AWS services like GuardDuty, Security Hub, and Amazon Detective for both detection and containment. For those preparing for the AWS Certified Security - Specialty SCS-C02 exam, well outline the knowledge and hands-on skills required to master resource isolation, ensuring youre prepared for real-world incidents and exam success.
